Description

YACHT WITH A TOP DECK HAVING A VARIABLE SURFACE AREA

The invention relates to a yacht provided with a top deck of variable surface area.

In the yacht construction industry a structure of a yacht, in particular a motor yacht, is known wherein a superstructure consisting of one or more inner decks located one above another protrudes above the hull. An inner deck is for instance adapted for recreation and accommodation, and an inner deck for the steersman of the yacht. As additional outside space, an independent outer deck which is open can be provided on top of the superstructure. This outer deck is also referred to as sundeck or top deck. Such a top deck is also referred to as bridge fly-deck or flybridge.

In addition, a support construction on which navigation and other equipment is arranged is often present on the open top deck in motor yachts. This construction is referred to in the field as the mast. This mast consists of a vertical support carrying a horizontal mast board on which the navigation equipment is disposed. The mast board itself is often embodied such that it spans the width of the top deck and part of the length of the top deck. The mast board thus has a second function as sun awning. In a common design the mast-is embodied on the basis of two upright panels on either side of the top tank on which the transverse mast board rests. This design is often referred to as a

goal-port' mast. Such a design is particularly common for motor yachts with the length of 20 m or more.

For streamlining purposes and in order to manoeuvre the vessel, it is generally desirable when sailing with a yacht to limit the surface area of the top deck to the upper surface of the superstructure, so that the top deck does not protrude outside the contours of the superstructure. This is particularly desirable in situations where the space available for the vessel is limited, such as in berths, and at bridges or locks. Conversely, the steersman may wish the top deck of the motor yacht to have a larger dimension at a berth with sufficient space or when travelling at lower speeds. In addition, it has been found that the upright panels of a goal port mast at the position of the top deck adversely affect the stability of the yacht because they catch a great deal of crosswind and, due to their weight at relative height, contribute toward an increase in the height of the centre of gravity of the yacht.

The invention has for its object to meet the above outlined general requirement, and moreover provide a solution to the stated drawbacks of the known designs of goal port masts. At the same time the invention may not detract from the design of the top deck and of the yacht in general.

The above stated object of the invention is achieved with a yacht according to the appended claims.

According to the first aspect, the invention relates for this purpose to a yacht, comprising a hull and a superstructure protruding above the hull, wherein a top deck which is open is provided on the upper side of the superstructure, characterized in that the superstructure comprises one or more movable top deck panels which can be connected to the surface of the top deck in order to enlarge the overall surface area, wherein the top deck panels are movable between an unused position and a position of use, wherein the top deck panels are provided at the sides of the top deck and can be connected in transverse direction of the yacht to the surface of the top deck, and wherein the top deck panels are movably coupled to the superstructure by means of a pivot connection. In the position of use the panels are in a position to enlarge the overall surface area, and in unused position the top deck panels do not have this function. The option is thus provided of enlarging the surface area of the top deck as desired.

Since a top deck has dimensions which are usually relatively narrow and long, it is advantageous to obtain a surface area enlargement in transverse direction. It is recommended here to provide a top deck panel on both sides, most preferably in a symmetrical design. A panorama terrace or sky terrace is thus formed by the top deck panels in the position of use.

Owing to the pivot connection the panels can be easily folded in and out to respectively an unused position and a position of use. It is simple using the pivot connection to place the panels such that they connect to the top deck, i.e. at the position of this pivot connection.

The invention thus provides the user of the yacht with the option of enlarging the surface area of the top deck in transverse direction. The invention achieves this in an elegant manner, wherein because of the pivot connection the top deck panels are incorporated in the general design of the yacht. The top deck panels are in other words integrated into the design, wherein in the position of use and in unused position they form one whole with the superstructure.

In the case of strong crosswind it has moreover been found advantageous to position the top deck panels in the position of use, since the lateral surface area of the yacht is thus reduced, whereby the crosswind has less impact on the position of the yacht. Furthermore, the centre of gravity of the yacht is simultaneously decreased, this further contributing toward a more stable position during crosswind.

The advantage of an integrated design applies particularly in the case of a yacht wherein in unused position the top deck panels stand upward, and in the position of use the top deck panels are positioned in the plane of the top deck. This is because in upward standing position the top deck panels form one whole with the upward lines of the superstructure, this contributing toward the integrated design of the yacht.

In the yacht according to the invention the top deck is preferably provided with a mast comprising a support

construction having a horizontal mast board thereon, wherein the movable top deck panels form a continuous unit with the mast when the top deck panels are in the unused position. Such a design contributes in even greater measure toward the integrated design of the yacht.

Such a design makes it possible to have the top deck panels in the unused position blend visually with the mast, wherein the panels are incorporated in the streamlining and the general design of the yacht. The top deck panels thus appear as a part of the support construction, as if they are the upright panels on which the mast board rests. The mast board advantageously rests on a support construction of individual uprights which take a slender form, i.e. have a relatively small lateral surface area at a given length. Compared to the top deck panels, such uprights have a negligible effect on the centre of gravity of the yacht, or on the sensitivity to crosswind.

It is especially recommended that the yacht according to the invention comprises top deck panels which are provided with fixed enclosures disposed along the outer edge of the top deck panels. The fixed enclosures have the function of a railing preventing passengers from falling overboard. Such a fixed enclosure is easy to incorporate in the top deck panel, and is preferred to a detachable enclosure, which is less practical (separate components are easily lost; stowage space is required) . The placing thereof moreover involves the risk of a fall for those arranging the enclosure.

The yacht according to the invention preferably comprises a pivot connection comprising a hydraulically or pneumatically driven lever for moving the pivot connection. Using such a construction sufficient force is generated to move such a deck panel (which can for instance weigh 1000 kg) . Such an arm can moreover produce sufficient load-bearing capacity to hold the panel stably in the position of use while the panel is loaded by passengers present thereon.

The yacht according to the invention more preferably comprises a pivot connection comprising a motor drive for moving the pivot connection, which drive preferably comprises a gear transmission such as a worm with a worm wheel. With such a construction sufficient force is also generated to move such a deck panel and enable stable holding thereof in the position of use. It is particularly recommended to apply a worm with worm wheel because this meets the set requirements extent.

In a subsequent preferred embodiment of the yacht according to the invention the top deck panel is provided with a stop which in the position of use lies against the superstructure. In order to achieve the load-bearing capacity required for the panel in the position of use, it can be advantageous to make such an additional provision, whereby an extra supporting surface is created, in addition to the load-bearing capacity provided by the pivot connection itself.

In the yacht according to the invention the mast board is more preferably displaceable in the longitudinal direction of the yacht. The mast board which spans a part of the top deck in longitudinal direction can thus be moved forward. The shading effect of the mast board is therefore displaceable in accordance with the wishes of the user.

The surface area which is freely accessible from above is moreover enlarged at the rear of the top deck. The top deck can thus be made suitable as a landing site for a helicopter. Displacing of the mast board moreover has the advantage that in the displaced situation it protects the rest of the yacht from downwash generated by a helicopter.

The mast board can for instance be connected slidably or rotatably to the support construction using means known to the skilled person.

In the yacht according to the invention the support construction is preferably movable between a starting position and a translation position. The support construction consists for instance of a system of rods, wherein at the bottom the rods are connected pivotally to the top deck and at the top are connected pivotally to the mast board. In starting position the mast stands in the usual position and in translation position the mast board is moved forward, wherein it can also take up a lower position.

It is recommended that the support construction brings about a displacement in longitudinal direction of the yacht as well as a height displacement. When lowered, the wind-turning effect of the mast board is increased, this also being advantageous during landing and take-off of a helicopter.

This construction moreover allows the mast to drop downward as a whole so that the height of the yacht is reduced. This is highly advantageous for instance when passing under low bridges.

The combination of outward folding top deck panels with a mast board adjustable in height and longitudinal direction is highly advantageous, particularly for the purpose of reducing the height of the yacht .

The invention is further elucidated with reference to the accompanying figures, which show different preferred

embodiments of the invention, and in which

Figure 1 is a side view of a yacht according to the invention; Figure 2 shows in perspective and in detail the top deck with top deck panels in unused position;

Figure 3 is a top view of the top deck with top deck panels in position of use;

Figure 4 shows in perspective the top deck of figure 2, wherein the mast board is displaceable;

Figure 5 shows a partially cut-away side view of an embodiment of a pivot connection between the superstructure and a top deck panel;

Figure 6 shows a partially cut-away side view of an embodiment of a pivot connection between the superstructure and a top deck panel;

Figures 7A and 7B show in cross-section two embodiments of a pivot connection between the superstructure and a top deck panel .

Figure 1 shows a yacht 1 with a superstructure 2 protruding above hull 4, wherein a top deck 6 is present on superstructure 2 and has thereabove a mast board 8 on which is arranged navigation equipment 10 such as radar and antennas.

Figure 2 shows top deck 6 of figure 1 with a support construction consisting of uprights 20 supporting mast board 8. In unused position top deck panels 22 are disposed at the sides of the top deck. Panels 22 connect at the top to the mast board and connect at the bottom to the outer edge 24 of top deck 6. In the unused position the top deck panels 22 thus form a visual whole with the yacht and the mast, as also shown in figure 1.

Figure 3 shows top deck panels 22 in folded-out position of use. Panels 22 are connected via pivot connections 30 to top deck 6. Uprights 20 support mast board 8. Panels 22 are provided with a wooden floor 32 similar to the floor of top deck 6. In accordance with the proportions in the figure, a doubling of the width of top deck 6 is obtained at the position of panels 22. This moreover makes the sensation of space on the top deck considerably greater since the top deck is no longer purely elongate.

Figure 4 shows a top deck 6 wherein mast board 8 is displaced forward by making use of movable uprights 20 connected with a pivot construction 40 to the top deck. Uprights 20 are connected to mast board 8 with a pivot construction 42. A helicopter 46 is shown at the rear of top deck 6 in order to illustrate that the top deck is suitable as landing place. In the figure the top deck panels stand upright, but can if desired also be folded out as according to figure 3. This further increases the space for a helicopter. The mast board 8 situated in the foremost position in figure 4 is clearly lowered in height relative to the original position. This lowering has the consequence of enhancing the function as wind-break for the top deck.

Figure 5 shows a top deck panel 22 which is arranged on the outer side of superstructure 2 and which protrudes partially above the outer edge or railing 24 of the top deck. On either side of panel 22 a motor 50 driving a rotation shaft 52 is built into and fixed in superstructure 2. The rotation shaft is built into panel 22 and connected fixedly thereto. Motor 50 is thus able to move panel 22 between the shown unused position and the position of use (shown in figure 3) .

Figure 6 shows an alternative pivot connection relative to figure 5. The pivot connection is constructed from a hydraulic cylinder 60 connected movably to a lever 62 which is connected movably to a rotation shaft 64. Cylinder 60 is fixedly connected to superstructure 2 and the rotation shaft is fixedly connected to panel 22. Panel 22 can thus be moved between the shown unused position and the position of use (shown in figure 3) .

Figure 7A shows in cross-section an embodiment of a pivot connection according to figure 6, with like numbered components. As addition to figure 6, there is provided as component of panel 22 a stop 70 which, when tilted to the right to a folded-out horizontal position, enters cavity 72 in superstructure 2. In the folded-out end position the stop lies against superstructure 2, against the upper side 75 of cavity 72. Also shown is an upright edge 74 which bounds the outer edge of panel 22.

Figure 7B shows a cross-section similar to figure 7A, wherein the stop and corresponding cavity are omitted. Sufficient load-bearing capacity is provided here by the pivot connection itself and the end surface 76 of the panel, which in the folded-out position supports against the superstructure.
